If you purchased a brand new computer today with all the latest security software and plug it into the Internet, how long would it be before the first hacker probed it? Answer : About four hours...
Probing? 4 hours? I attached lately a new FW to my ISPs network, it took less than ONE minute until the first knocked on the wall! ;-)However, the interesting fact would be, how strong such a new machine with all the latest (security) software installed would remain unhacked!?!
Knowing that you can get hacked (sorry, probed) every day, why are still so many products open by default? No initial passwords, disabled by default, not locked down by default, etc., etc., etc.
